Find the z value such that the area under the standard normal distribution curve between 0 and z value is 0.3962 or 39.62%.a. 1.18b. 1.26c. 1.34 d. 1.42

Respuesta :

Let's draw a normal distribution.

First, we have to add the percentages.

[tex]0.50+0.3962=0.8962[/tex]

Then, we use the following chart to find the z-value of 0.8962.

According to the table, the z-value is 1.20.

Therefore, the correct answer is a. 1.18.
